Spreading Film: The film is spread out on the water surface of the dipping
basin. The water bath is heated and kept at a constant 30°C. The film
dissolves and only the ink image remains floating on the water.
Activating: The ink is sprayed with an activating material so that it becomes
adhesive. After spraying with activator, the ink must sit for 3 minutes.
Transferring: The parts are dipped into the water through the layer of
liquefied ink. The image is pressed to the parts evenly by the pressure of
the water. If there are several parts to be dipped, they are mounted to a
fixture and dipped simultaneously.
Washing and Drying: The printed parts are washed to rinse off remaining
pieces of film, and dried. Due to the exposure to water here, Z Corp. parts
must be well infiltrated and finished completely with the primer, even if the
image is to be partially applied.
Top Coating: The parts are clear coated or varnished to protect the
printed surface. A varying degree of gloss can be achieved by using
different top coats. Polishing completes the process.
Presenting: The finished parts can now be used. The surface can be very
durable and scratch resistant – depending on the top coat used, so the finish
will stand up to many functional applications.
